Tanzania [10]

Complete Question

We can calculate EEE, the amount of euros that has the same value as DDD U.S. Dollars, using the equation

E= 17/20 D

a) How many euros have the same value as 1 U.S. Dollar? euros

b) How many U.S. Dollars have the same value as 1 euro? dollars

Answer:

a) 0.85 euros

b) 1.18 dollars

Step-by-step explanation:

The equation is given as:

E= 17/20 D

a) How many euros have the same value as 1 U.S. Dollar? euros

E = 17/20D

D = 1 dollar

Hence:

E = 17/20 × 1

E = 0.85 euros

b) How many U.S. Dollars have the same value as 1 euro? dollars

E = 17/20D

E = 1 euro

1 = 17/20D

D = 1 ÷ 17/20

D = 1 × 20/17

D = 1.1764705882 dollars

D = 1.18 dollars

(Need 3 answers) An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n) =
Strike441 [17]

Answer:

  • See below

Step-by-step explanation:

<u>According to the model, the equation is:</u>

  • P(n) = 3450*bⁿ

Based on the equation, the initial number of insects is 3450

<u>If b = 1.75, daily growth rate is:</u>

  • 1.75 - 1 = 0.75 = 75%

<u>If  we get P(4) = 55200, find the value of b:</u>

  • 55200 = 3450*b⁴
  • b⁴ = 55200/3450
  • b⁴ = 16
  • b⁴ = 2⁴
  • b = 2
